Abstract

A method includes receiving a plurality of audio signals. Each of the plurality of audio signals includes audio packets, wherein one or more audio packets from each of the plurality of audio signals is coded with an audiometric, the audiometric including an acoustic measurement from a conference site. The method further includes, for each of the plurality of audio signals, extracting an audiometric from one or more audio packets and selecting an active audio signal based on the extracted audiometrics. In addition, the method includes determining a change in the active audio signal and in response to determining a change in the active audio signal, updating a media forwarding table, the media forwarding table including a directory for routing one or more of the plurality of audio signals. The method further includes distributing audio packets to one or more conference sites in accordance with the media forwarding table.
